Architected, Designed and Implemented
BDS - Brick data store known as BDS is a distributed in-memory database developed and used in Rtbrick for all routing and access protocols. BDS helps reduce coding and garbage collection complexity for applications. Infrastructure is REST API enabled and Grafana integrated with our own lightweight TSDB. Key features of BDS
1. Table and object creation
2. Stored procedure calls
3. State compression
4. Qrunner for timers
5. Table Snapshot to disk
6. Memory manager
7. Jobs for application
8. Pool manager for label and IP
9. lightweight TSDB integrated with Grafana (simple Json API)
10. In memory logging (Graylog and syslog plugin)
PUBSUB - A lightweight in-memory PUBSUB. With the help of PUBSUB all the applications will be able to communicate with each other and keep the database in sync with a low overhead ack mechanism. Key features of PUBSUB
1. Table subscription
2. Object based subscription
3. Attribute based subscription
4. Hash based subscription
Access Protocol - As part of the access portfolio PPPOE, L2TP (LAC and LNS) and radius client.
